The original include/asm-generic/ioctl.h did not allow overriding
the values of _IOC_{SIZEBITS,DIRBITS,NONE,READ,WRITE}, so it
was initially not possible to use it.
Nowadays, you can simply use the same approach as powerpc:
#ifndef _ASM_MIPS_IOCTL_H
#define _ASM_MIPS_IOCTL_H
#define _IOC_SIZEBITS 13
#define _IOC_DIRBITS 3
#define _IOC_NONE 1U
#define _IOC_READ 2U
#define _IOC_WRITE 4U
/*
* The following are included for compatibility
*/
#define _IOC_VOID 0x20000000
#define _IOC_OUT 0x40000000
#define _IOC_IN 0x80000000
#define _IOC_INOUT (IOC_IN|IOC_OUT)
#include <asm-generic/ioctl.h>
#endif /* _ASM_MIPS_IOCTL_H */
This would indeed be a cleaner fix.
